Abstract
An electrical or electronic part having excellent resistance to moist heat, such as a coil bobbin, a condenser case, an IC carrier, a plug, a socket or a fuse case, formed from a polybutylene naphthalenedicarboxylate resin as a raw material; and a flame-retardant resin composition and an electrical part therefrom are also provided. The flame-retardant resin composition exhibits high fluidity and forms little burr, and the electrical part has excellent flame retardancy and well-balanced properties.
Claims17
An electrical or electronic part formed from a polybutylene naphthalenedicarboxylate resin as a raw material.
An electrical part formed from a resin composition, wherein said composition comprises
- (A) a polybutylene naphthalenedicarboxylate resin,
- (B) a brominated flame retardant, and
- (C) a flame retardant aid comprising as a main component at least one of antimony trioxide and antimony pentoxide.
A flame-retardant resin composition comprising
- (A) a resin or a resin mixture selected from the group consisting of a polybutylene naphthalenedicarboxylate resin, a copolyester resin in which the content of the total of a butylene group and a naphthalenedicarboxylate group is at least 60% by weight, and a resin mixture containing at least 60% by weight of polybutylene naphthalenedicarboxylate and the balance of other thermoplastic resin,
- (B) 4 to 25% by weight of a brominated epoxy-containing flame retardant,
- (C) 2 to 15% by weight of a flame retardant aid comprising as a main component at least one of antimony trioxide and antimony pentoxide, and
- (D) 0.05 to 10% by weight of a polytetrafluoroethylene resin prepared by an emulsion polymerization method.
